Model Learning Cycle 7E dalam Pembelajaran IPA Terpadu

Artikel ini bertujuan untuk menjelaskan hakikat model learning cycle 7E. Model learning cycle 7E merupakan model pembelajaran yang berbasis konstruktivisme yang terdiri dari tujuh fase berupa Elicit, Engage, Explore, Explain, Elaborate, Evaluate, dan Extend yang terorganisasi dan berpusat pada siswa sehingga siswa secara aktif menemukan konsep sendiri. Pada fase Elicit, guru berusaha mendatangkan pengetahuan awal siswa, pada fase Engage, guru mengajak dan menarik perhatian siswa. Siswa diberikan pengalaman langsung untuk berkeksplorasi pada fase Explore dan menjelaskan apa yang ia dapatkan dari hasil ekslporasi pada fase Explain. Selanjutnya pada fase Elaborate siswa menerapkan simbol, definisi, konsep, dan keterampilan pada permasalahan. Pada fase Evaluate, guru menilai siswa, dan kemudian pada fase Extend siswa memperluas pengetahuannya dengan menjelaskan contoh penerapan konsep yang telah dipelajari ataupun mencari hubungan antara konsep yang mereka pelajari dengan konsep lain yang sudah atau belum mereka pelajari. Model ini dapat menumbuhkan keterlibatan siswa dalam pembelajaran secara aktif. Berdasarkan penelitian yang telah dilakukan oleh peneliti pendahulu, dengan model learning cycle 7E dapat meningkatkan hasil belajar dan keterampilan berpikir kritis. Model ini cocok apabila diterapkan dalam pembelajaran IPA karena hakikat IPA yang meliputi empat unsur (sikap, proses, produk, dan aplikasi) dapat muncul dalam fase learning cycle 7E

Placement of inertial measurement units in Racket Sports: Perceptions of coaches for IMU use during training and competition

While inertial measurement units (IMU) have become an integral part of sports performance analysis, upper body-mounted IMUs have been found to exhibit poor reliability in measuring lower-limb loading. In racket sports, IMUs have been placed in a number of positions on the upper body, lower body and racket in a research setting. A potential limitation to the concurrent use of multiple IMUs is that coaches may be reluctant to allow their athletes to wear the units during training and competition due to concerns that the units would interfere with athlete movement. This study seeks to understand the perceptions of racket sports coaches towards the use of IMUs in training and competition. A total of 58 racket sport coaches responded to a survey on the use of IMUs during training and competition. Based on the responses, 96.6% (56 out of 58) of coaches indicated that they would allow their athletes to wear IMUs in training, while 65.5% (38 out of 58) would allow their athletes to wear IMUs during competition. For use in training, 9 of the 14 suggested IMU placements received significant positive responses. However, none of the suggested IMU placements received significant positive responses for use during competition and 11 of the 14 received significant negative responses. This suggests that while coaches understand the benefits of collecting data from IMUs during competition. Despite this, for use in training, a number of upper and lower body-mounted IMUs placements have the potential to be part of regular monitoring in racket sports

Study on Characteristic of Bed Material and Bed Load Discharge in Sungai Jemberau, Tasik Chini

Tasik Chini is located in the state of Pahang about 100 km from Kuantan, the capital of the state of Pahang. Most of the lowland within the study area has been converted into agricultural and including rubber and oil palm plantations and mixed crops. This logging and mining activities gave impact to sediment characteristics and discharge. The purpose of this study was to identify the bed material characteristics and to determine the bed load discharge in Sungai Jemberau at Tasik Chini. Bed material sample was collect at Sungai Jemberau in 24 November 2016, 1 December 2016 and 5 March 2017. Bedload discharge also measured between these date. The bed load discharges also estimate by using Duboys and Schoklitschequation to identify the suitable predicted method for this area. From the analysis of the results, DuboysEquation was more suitable to predict and estimate the bed load discharges for Sungai Jemberau at Tasik Chini because the predicted value closer to measured value

Does Extract of Pleurotus sajor-caju affect Liver Enzymes and Histological Integrity?

Pleurotus sajor-caju (PSC) was believed to have both antihyperlipidemic and hepatoprotective activities. The present study aimed to investigate the effect of PSC on liver enzymes and histological integrity. This study used five groups of rats fed with ghee in the ratio 32g ghee per 68g pellet to induce hypercholesterolemia and one group was fed on cholesterol free basal diet. Rats treated with 100 mg/kg of PSC for a month was found to have an effect on the liver enzymes activities since plasma alkaline phosphatase (ALP) concentration in this group showed a significant reduction (P<0.05) and a higher percentage reduction (66.01%) as compared to 20 mg/kg-PSC and 200 mg/kg- PSC treatment groups. The plasma aspartate aminotransferase (AST) and alanine aminotransferase (ALT) only showed a mild increased by 35.04% and 15.00% respectively in 100 mg/kg-PSC treatment group and there was no significant increased (P>0.05) found in these both AST and ALT concentrations. Atorvastatin treatment also showed reduction in ALP enzymes but no significant reduction (P>0.05) as compared to 100 mg/kg-PSC treatment group. On the other hand, plasma AST and ALT in 20 mg/kg of atorvastatin treatment were increased in percentage by 275.97% and 112.50% respectively indicated the adverse effects of statin in term of elevation of plasma enzymes activities. On the histological part, there was no significant finding in the micrograph study between treatment and hypercholesterolemic (HPC) liver rat. The micrograph of rat liver treated with 100 mg/kg PSC showed smooth and clear surface of hepatocytes compared to HPC group

Socializing One Health: an innovative strategy to investigate social and behavioral risks of emerging viral threats

In an effort to strengthen global capacity to prevent, detect, and control infectious diseases in animals and people, the United States Agency for International Development’s (USAID) Emerging Pandemic Threats (EPT) PREDICT project funded development of regional, national, and local One Health capacities for early disease detection, rapid response, disease control, and risk reduction. From the outset, the EPT approach was inclusive of social science research methods designed to understand the contexts and behaviors of communities living and working at human-animal-environment interfaces considered high-risk for virus emergence. Using qualitative and quantitative approaches, PREDICT behavioral research aimed to identify and assess a range of socio-cultural behaviors that could be influential in zoonotic disease emergence, amplification, and transmission. This broad approach to behavioral risk characterization enabled us to identify and characterize human activities that could be linked to the transmission dynamics of new and emerging viruses. This paper provides a discussion of implementation of a social science approach within a zoonotic surveillance framework. We conducted in-depth ethnographic interviews and focus groups to better understand the individual- and community-level knowledge, attitudes, and practices that potentially put participants at risk for zoonotic disease transmission from the animals they live and work with, across 6 interface domains. When we asked highly-exposed individuals (ie. bushmeat hunters, wildlife or guano farmers) about the risk they perceived in their occupational activities, most did not perceive it to be risky, whether because it was normalized by years (or generations) of doing such an activity, or due to lack of information about potential risks. Integrating the social sciences allows investigations of the specific human activities that are hypothesized to drive disease emergence, amplification, and transmission, in order to better substantiate behavioral disease drivers, along with the social dimensions of infection and transmission dynamics. Understanding these dynamics is critical to achieving health security--the protection from threats to health-- which requires investments in both collective and individual health security. Involving behavioral sciences into zoonotic disease surveillance allowed us to push toward fuller community integration and engagement and toward dialogue and implementation of recommendations for disease prevention and improved health security
